FS:B&O ICEpower 200ASC modules - 20PCS

Am I missing a point here?

The ICE power modules accept both balanced and un-balanced inputs according to the specs (unbalanced requires negative input tied to GND).

Is this to improve the handling of balanced inputs compared to the "native" balanced input of the module?

I didn't realize the module alows you to tie the negative input to ground for single ended input. 😱

Also, the THAT1200 is a balanced to single ended IC; I don't see what the point of using it would be. 😕

In Jeff Rowland's design,the 200ASC module's input is in single-end mode.
That is,the THAT 1200 convert balanced signal to un-balanced signal and feed un-balanced signal into 200ASC.

THAT 1200 also work with un-balanced input.

I think the only reason for it is to increase the imputimpedance from 10k to 48k, making it a standard load?

Seems odd to konvert balanced signals to single-ended and sending it 10cm to a balanced input....

I hardly think the performance will be better with more redundant electronic in the signal path.

Rotel uses the same ICE modul direct in one of their amps...spec'ed with 9k99Ohm/1.25V input data...

OKaaayyy...!? :xeye:

So, we have a power-amp module, which accepts either balanced or un-balanced input.

This is connected to a THAT1200 thingy, which accepts either balanced or un-balanced input. (What kind of a name is THAT1200, anyway!?)

This is giving me a headache... :dead:

I suppose it's all about CMRR on balanced signals, but for people like me who don't have a balanced source signal, it's hard to see any purpose with THAT (pun intended 🙂 )

Safety issue resolved

Hi folks,

I know it sounds like a desperate move, but I ended up reading the **** manual. 😀

In the document YFW linked to (in the beginning of this thread), it actually specifies that it's a class II unit. (page 24).

Thus, I am not sure if I would attempt using the center hole as a ground point, because it's not specified to be used as such.
